Abstract Carbon dots with Nitrogen-doped (N-CDs) were prepared from easy hydrothermal method by broad bean and 1,2-ethanediamine as precursors. The prepared N-CDs were authenticated by ultraviolet-visible (UV-vis) absorption spectra, fluorescence spectra, displayed that the prepared N-CDs owned excellent fluorescence properties. X-ray photoelectron spectroscopy (XPS) and Fourier Transform Infrared Spectroscopy (FT-IR) verified that N-CDs carrying many different hydrophilic groups (for example hydroxyl, carboxyl/carbonyl, amide, amino, etc.) on the surface. Besides, the prepared N-CDs exhibited outstanding advantages including low-toxicity, satisfactory biocompatibility, and excellent chemical stability. More prominently, the prepared N-CDs could sensitively and selectively detect heavy metal Hg2+ ion both in water samples and in HeLa cells.
